DataList Control for ASP. NET data binding, asp. netdatalist The DataList control is a control in. NET. The DataList control presents data in the form of a table (you can edit it in the property generator). With this control, you can use different la s to display data records (using template editing), for example, sort

and provides users with the data to view the displayed data. The Controller built using the MVC mode should be: Operations required to update a model based on user interaction The Controller should not: Contains the logic for managing the appearance of data (that is, view work) Contains the logic for managing data persistence (that is, model work) Understanding View The view contains the logic required to display data to users or capture data f

Many people who have done program performance optimizations, or who are concerned about the performance of process programs, should have used various caching techniques. And the cache I'm talking about today is specifically about the cache, and we can use the cache that Httpruntime.cache accesses, not other caching techniques.I used to simply mention it in my "My idea of the ASP. NET Core Object" blog, and
